RADIATOR.

SPECIFICATION forming part of Letters Patent No. 375,493, dated December 27, 1887. I

Application filed May 25, 1857. Serial No. 239,275. (No model.)

To all whom, it may concern.-

Beit known that I, PATRICK J. KELLY, of Elizabethport, in the county of Union and State of New Jersey, have invented a new and useful Improvementin Radiators,of which the following is a speciication.

My invention relates to those radiators which are designed for heating by hot water or steam, and, indeed, for cooling by the cir- 'culation of a refrigerant-as brine-through them, and which are formed by cast-metal sections secured together side by side and severally composed of a base pcrtion having chambers, and a U-shaped tube or' tubes for circulation springing from the base portion and formed integral therewith.

My invention consists in a radiator embodying novel features of construction, hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure lis a partly/#sectional elevation of a radiator embodying my invention. Fig. 2 is an end view of the radiator. on about the plane ofthe dotted line x x, Fig. 1; and Fig. et is a transverse section on about the plane indicated by the dotted line fz/ y, Fig. 3.

Similar letters of reference designate corresponding parts in all the figures. 3c Thevradiatoris composed of cast-metalsections, each 'composed of U-shaped tubes A and the base portion B, and the sections are secured side by side by bolts C, extending through the base portions B of the sections. As here shown, the hollow base portions have cast in them tubular studs c2, receiving the bolts through them,and packing, s, ofpaper or other niaterial,may be introduced between the base portions of adjacent sections to form tight 4o joints. The sections are arranged so that the base portions B have their length transverse to the length of the radiator, and the tubes A of each section are arranged in a line or row which extends transversely across the radiator.

The inlet or supply pipe D, as here shown, communicates th one side ofthe radiator at the end of one end section of the radiator, and the outlet-pipe D communicates with the op-l 5o posite end of the other end section,

Fig. 3 is ahorizontal section` As here represented, each base portion B has two approximately U'- shaped tubes, A, formed in one integral piece with it andA lying in the same plane With each other, and each base portion B is constructed with chambers 5 5 ce at opposite ends, and with a chamber, c3, intermediate between the 'other two. I will presume, for the purpose of illustration, that the section shown in Fig. 4 is the lefthand section of Fig. 3,and that the steam or hot wa- 6o ter enters through the pipe D and into the chamber c. From the chamber e the steam o r hot water passes in the direction indicated by the arrows, Fig. 4, and through the iirst tube A to the chamber eiland thence through e' 5 the second tube A to the chamber c', and from the chamber c the steam or other fluid passes through an opening, c4, in the wall bev tween the iirst and second sections, and into the second section at the left hand of Fig. 3, 7o and in said second section it passes rst from the chamber c through the tube A to the chamber c, and thence through the second tube of said second section to the chamber c', and from said chamber c it passes through a corresponding opening, c4, to the chamber c of the third section, looking 'from the left hand OfFig. 3.

I am aware that it is not broadly new to construct a radiator of sections which severally comprise a base portion, with two cham- 8 0 bers and a U -shapedtube springing from the base portion and formed integral therewith, the sections being secured side byside, so that a continuons passage for circulation is formed through their base chambers and tubes, and I 8 5 do not claim such a construction, broadly, as of my invention. If a large radiating-surface were desired,it could be obtained with a radiator of the above kind only by making the radiator very long; but by my invention I pro- 9o vide a constructionwhereby in a large radiator the same advantages of positive circulation and simple and inexpensive construction can be secured in a radiator having its width in about the usual proportion to its length, and much greater than in a radiator of the kind above referred to, having a single row of U -shaped tubes extending lengthwise of it.

What I claim as my invention, and desire to secure by Letters Patent, is Ioo The radiator herein described, consisting of site sides of the radiator with euch other to east-metal sections, each composed of u base provide for circulation through the base por- Io' portion,l3,m1d :mrow of U-shaped tubes, A, the tions and tubes of the sections in succession, sections being secured together side by side substantially as herein set forth.
